A polytheistic religion is one in which more than one deity (god) is recognized and worshiped, such as Hinduism and Paganism.
The best examples would be the ancient religions followed by the Babylonians, Egyptians, Romans, Etc. Today there are numerous people in the world who follow folk religions, pagan traditions and practice animism. Another good example would the religion of some of the "Kalash People" of North-West Pakistan. These people are descendants of Alexander the great's army and amazingly, they follow the same religion that people of ancient Greece followed!
A lot of people would agree that Hinduism is polytheistic. However this can be debated. Some scholars within Hinduism argue that the multiple gods and goddesses that are worshiped by Hindus are actually different representations/incarnations of a single god. Hence Hinduism can be argued to be polytheistic or monotheistic depending on which way you look at it.
Hinduism is the only major polytheistic religion that worships multiple gods and goddesses.
